RECEPTACLE CLOSURE.

Application filed May 10, 1923. Serial No. 637,930.

To all whom it concern: Be it known that I, AUG STUS, L. ME- RoLLE,'acitizen of the United States, residing at Brooklyn, in the county .ofKings and in whichexceptionally strong and sub-' stantial threadelements are provided.

A further and more detailed object is to provide a closure of this typehaving a wire.- edge formed thereon by turning up the mavterial at thebottom of the flange, and said said wire-edge being indented to provideinwardly projecting lugs upon the flange for engaging beneathprojections of the receptacle, and to form portions of the flange edgeto comprise relatively resilient ribs rectly above said inset portionsof the wirecontinuing thread-lik from said inset portions of thewire-edge whereby to insure uniform grip of the closurecircumferentially of the receptacle.

Other objects and aims of the invention, more or less specific thanthose referred to above, will be in part obvious and in part pointed outin the course of the following description of the elements,combinations, arrangements of parts and applications of principles,constituting the invention, and

' the scope of protection contemplated will be indicated in the appendedclaims.

In the accompanying drawings which are to be taken as a part of thisspecification, and in which, I have shown merely a preferred form ofembodiment of-the invention: y

Figure 1 is a side elevational view of a closure constructed inaccordance with this invention, the same being illustrated as applied onto a receptacle and a part of the view being shown in vertical sectionfor the disclosure of detailed construction.

Figure 2 is a detailed sectional View taken substantially upon the planeof line III-- III of Figure 1. I 1 I Figure 8-is a" fragmentary detailedview of a portion of the interior surface of the flange of the closureshowing one of the thread portions and: I,

Figure 4 is a bottom parts seen in Figure 3.

Referring to the drawings for describing in detail the constructiontherein illustrated, the reference character L indicates the receptaclewhich is of course open at its up per end and which may or may not beprovided with-anv annular outstanding bead 1 thereon spaced downwardlyfrom the upper endfof the receptacle, Between the bead and the upper endis provided suitable outedge 'view of the standing threads orpro'ections 2 with which the closure is inten ed to engage byinter-rotation of said] parts in the usual manner. a

. The reference'character G indicates generally the closure device thesalne being made up of a cover part 3 and an annular marginal flange 4provided thereon for de-' ending about the exterior of'the receptacle.The entire closure is formed, from a single piece of sheet metalpressed, or drawn, into shape.

The lower annular-edge of the'flange is bent upon itself to'provide anoutstanding wire-edge H. Above this "jwireredge the flange is providedwith suitable corrugations 5 by which the closure may-begripped forscrewing it onto and off of the receptacle. a

These corrugations are spaced above the wire-edge so as-to leaveanexpanse of the flange, as indicated 6, for carrying, the threadindentations 7.

There may be as many thread indentations circumferentially of the flange as desired. Ordinarily however fouraresuflioi'ent and it will ofcourse be'understood that there is a similar number 'of the projections2 formed upon the receptacle.

At the lower ends of each of the threadindentations, that is where saidindentations meet the wire-edge H, said wire-edge s bent inwardly torovide inset portions 8 directly in continuatlon of said threadindentations l and serving thereby as a'very strong and substantialreinforcement for the lower end of said thread indentations. They also'provide smooth and attractively rounded ter- I minations of said'threadindentations. As a matter of fact, the thread indentations extend from apoint above the wire edge in an inclined plane downwardly to and acrossthe wire edge without interruption, the material of the wire edge at thelower ends of the thread indentations being bent bodily inwardly as apartof the thread indentations.

A most important characteristic to be noted in connection with thisstructure is that whereas the lower end, or beginning, of each of thethread portions of the closure is relatively strong and rigid, due: tothe presence of the plurality of thicknesses of metal comprising thereinforcing band or wire-edge H, yet the portion of the thread above thewire-edge, comprisingas itdoes only a single thickness of metal, isrelatively weak and resilient and is thereby capable of yielding to acertain and desired extent which will permit the several thread portionsto assume uniform grip upon the receptacle when the closure is beingrotated relative to the projections 2.

Although the upper portions of the threads are" relatively resilient yetthey are efliciently held against undue spreading and the like by reasonof the presence of the reinforcing band constituted by the wire-edge.Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is: s p

1. A receptacle closure comprising a cover portion and a flange portion,the material of the flange being bent upon itself to provide a wire-edgeat the lower edge of the flange,

the materialof the flange being also bent to provide an inclined threadindentation therein, and said wire-edge being bent to provide anindentation standing as a continuation and constituent part of saidthread indentation.

2. A receptacle closure comprising a cover portion and a flange portion,a wire edge formed upon said flange portion at the lower edge .thereof,thread indentations formed u on the flange portion being relatively resiient above their lower end portions, and said wire edge havingindentations therein arranged to constitute the lower ends of saidthread indentations and to thereby render said lower ends relativelyrigid and unyielding.

3. A receptacle closure comprising a cover portion and a flange portion,the material of the flange portionlbeing bent upon itself to provide awire edge at the lower edge of the flange portion, the material of theflange portion being also bent to provide a thread indentation therein,and said thread indentation extending longitudinally in an.

inclined plane from a point spaced. above the wireedge downwardly acrosssaid wire edge, the material of the wire edge being bent bodily inwardlyas a part of the thread indentation. r

In testimony whereof I aflix my signature.

AUGUSTUS L. MEROLLE.
